This round marker lamp emits orange light for side marking on agricultural tractors and trailed equipment. It mounts to the vehicle body or bracket using the two M5 threaded fasteners, with a hole spacing that matches standard lamp holders. The lamp operates on either 12 or 24 volt electrical systems. A failed lamp reduces the vehicle's visibility to other road users, particularly during field-to-road transport. On replacement, verify the gasket between the lamp base and the mounting surface is intact to prevent moisture ingress into the housing.
